What I'm looking for

I seek senior engineering roles where I can lead architecture and delivery of scalable, secure cloud-native systems, mentor teams, and drive DevOps automation in an Agile environment.

I am a Senior Java Full Stack Engineer with over 10 years building enterprise-scale applications across finance, insurance, and healthcare. I design and implement distributed microservices, RESTful and GraphQL APIs, and event-driven pipelines using Java, Spring Boot, Kafka, and cloud platforms to achieve high throughput and low latency.

I champion clean code, TDD, and security best practices while mentoring teams and automating delivery with Terraform, Docker, Kubernetes, and CI/CD pipelines. My work includes optimizing systems for performance (25,000+ TPS, 40% latency reduction), implementing HIPAA-compliant healthcare integrations, and delivering rich front-end experiences with Angular and React.
